I brush then rinse with Smartwash. I also wash my "Leonidas, Spartan beard" (as my wife calls it). Smoke just loves hangin' on to the beard.
Now, I only do all the above if I'm around people that care, such as the woman I live with and the beard washing only occurs if I smoke before bed. How can I "love" her if she can't stand the smoky beard?...By doing the above breath/beard treatment...that's how.
